How the SL014948 model number is decoded

envelope 240×320×80 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 740 kN and C0 1700 kN; with a C/C0 ratio of 0.44 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 198 kN, the limiting speed 1,110 r/min and the thermal reference speed 660 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.08 kN per millimetre of the 240 mm bore and 9.25 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 18.5 kg (18500 g) (0.72 g per mm² of the 320×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 240 mm bore puts this execution at the top of the HR1 range — the 320 mm outside diameter, 80 mm width and 18.5 kg mass are built for primary-industry load cases Reading SL0149: the DIN 5412-9 type code family NNC49, double-row full complement with split outer ring; the joining retaining rings must not be used to transmit axial force No angular compensation is built in: misalignment loads one roller row preferentially, so the housing and shaft seats for a 240 mm bore SL0149 must be machined parallel Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 320 mm outside diameter and 740 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 240 mm seat, and in construction machinery slewing drives the 18.5 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 80 mm width and the published 1700 kN static rating. There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact. The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.

Selection pitfalls — read before you substitute

• There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact.
• The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
